Hi All,
I am hoping someone can help me shed some light on the online backup process of a 2-node mysql cluster.
I have a functioning 2-node cluster serving a db worth of approx 3gig of data.
I noticed that when I create a backup by regular means (ndb_mgm -e "START BACKUP <ID>", the resulting "BACKUP-<ID>" directories under each node contain approximately 300Meg each.
I have ten days of backups so far, and only one of the BACKUP-<ID> directories on
one node contains 2.7G, while the corresponding backup directory on the second node
only 270M for that date.
My question is should I not be expecting each node to produce equal and large backup files (on the order of 3GB)? Ndb cluster does not support incrementals,
so it cant be that...
Your assistance is greatly appreciated.
Thanks!
